Application filed April 11.

Tool! whom, it may concern Be it known that I, JOSEPH J. hlEGIRIAX.

a citizen of the United States, and a resident of Bay Ridge, Brooklyn. in the county of Kings and State of New York. have invented certain new and useful Improvements in Dispensing Devices-of which the following is a specification.

This invention relates to means for delivering predetermined quantums of liquid from a'receptacle. andinore particularly to dispensing attachments for bottles.

The object of the invention is to provide a simple device whereby a predetermined amount of liquid is allowed to How from the interior of the bottle upon each tilting the flow heing automatically stopped after the passage of this predetermined amount or the lapse of a predetermined interval of time.

The device includes a delivery outlet arranged so that liquid fiOWS through it from the bottle into the glass or other receiver, when the bottle is tilted in the ordinary manner for pouring, and means controlled by the liquid for automatically stopping this How. Another equal quantity of liquid may he obtained in the same way, by first restoring the bottle to normal or upright position and again tilting it. The means for thus stopping the delivery flow includes a cont-rolling; chamber arranged to receive liquid during the act of pouring; from the dispensing outlet, and means for admitting air to the bottle to replace the liquid delivered. which airadmission means. is cut otf hy the liquid filling this chamber. The quantity of liquid delivered from the outlet depends upon the rate of flow into this chamber and the capacity of the chamber; consequently, the amount dispensed at each tilting; of the bottle may he varied by regulating either or both of these factors. The chamber and its inlet from the bottle are so arranged that when the latter is restored to upright position the liquid in the chamber drains hack into the bottle.

in the concrete embodiment. of the invention illustrated the device comprises a stop-- per having a delivery no/ale and a controlling chamber with a separate liquid inlet 'lr-oi'n the bottle, there being also an air inlet opening to said chamber andan air conduit leading from the chamber into the interior Specification of Letters Patent.

its contents discharged through the dispensing outlet and part enters the controlline chamber. the flow through the noszle continuing until the liquid fills or rises suiticiently high in the controllin; chamber to cut o'tt' the air connection to the hott-leflvhen the pouring is automatically stopped. The controlling chamber constitutes a species of trap or cut de sac, from which the liquid cannot escape. ut drains back intothe hettie when the latter is restored to normal position. Means are provided for varying the quantity delivered. and preferably this ad justment is etiected by varying the capacity of the controlling chamber. A "2'0 The invention includes various other into tures which will become apparent the specification proceeds. t

In the accompanying drmvings-iliust rat ing the attachment: Figure 1 s a vertical '75 longitudinal section of the same appiied to a bottle; Fig.2 is a vertical section at right angles to that of Fig. 1. parts beingshown in elevation; and Fig. 3 is a section on the line 3-3 of Fig. 1.. i

The preferred embodiment of the invention illustrated will now be briefly described.

The numeral 1 indicates a bottle, which may obviously he of any character. Thedevice has a stopper portion 2 for insertion in the neck of the bottle. it may be variously constructed, but as shown it comprises a llUllU W cork or gasket having a metal. tube or lining; 4. fitted therein and p'roirided with a cap plate 5 overlying the top of the portion This cap plate has an out-let opening (3. which communicates With the interior of the bottle and from which may project a delivery noznle or pipe. As shown there is a carved or inclined pipe 7 leading from the said opening and delivering into a nozzle 8, which materialiy Wider atthe hase than the said pipe and tapers toward its outer end. A. controlling chamber 8 of suitable form is mi-ichanicaliy connected with the stopper support; my means of two smalii pipes 10 and 11, which may be bent or curved as eiown. The pipe 10 constitutes a passage for permitting the. liquid to tint? from the hot-tie into the chamber 9 wile the bottle titted. fit one it is seen. an opening in the cap plate iii. v5

men a. the bottle. and at t other on it some d to the heel: weli '12 of the chat oar,

where its outlet may be flush with the inner side of said .wall. The pipe 11 passes through another opening in the cap plate 5, where it suitably secured, and is of a length to extend a considerable distance into the bottle. The outer end of this pipe 11 passes through the back wall 12 of the chamber 9, where it is secured in a tight manner, and preferably projects to a greater or less distance into the interior of the said chamber in advance of the said wall. The chamber 9 has an inlet arranged to permit air to enter the chamber and thence to pass by the pipe 11 into the interior of the bottle. The air inlet to the chamber 5) is preferably through the back wall 12, and it preferably has a tubular extension rearward from the said wall. This air inlet may be variously constructed, but as shown itis a short tube 13 open at its forward end to the interior of the chamber and partially closed at its rear end, leaving a small air opening 14. D

In operation, when the bottle is tilted 1n the ordinary manner to pour, liquid passes through the pipe 7 and the nozzle 8 into the glass or other recipient, and simultaneously liquid passes from the? bottle by the pipe '10 into the interior {it the chamber 9. The bore of the pipe 103s small, so that a sufiicient time period elapses before the filling of this chamber, and during the filling thereof liquid continues to flow from.

the nozzle. hen the liquid rises to the back wall 12, which in this position is the top wall, the admission of air to the bottle to take the place of the liquid flowing out is cut otf, and consequentlyfihe delivery of liquid from the nozzle ceases. hen the bottle is returned to upright position the liquid trapped in the chamber 9 drains back into the bottle through the pipe 10. Means are provided for varying the quan tity'of liquid thus delivered, andt-he said means preferably comprises a movable piston or wall 15 for the chamber 9. As shown this chamber is cylindrical, and the piston 15 is mounted slidably therein. It I will be understood that the piston will be suitably formed and arranged to insure a tight joint. It has a stem 16 projecting forward from the chamber and bent back over the side thereof, where it cooperates with suitable means for retai ing the piston in any one of a number (if graduated positions, which correspond to different quantities of liquid that may be delivered from .the nozzle. In the particular construction shown the retroverted portion 17 of the stem 16 moves in a longitudinal guide 18 on the side wall of the chamber, there being any suitable number of transverse. grooves 19 for receiving the upturned end 20 of the stem, to hold the piston against longitudinal movement after a desired adjustment has been eifected. Thus, the piston can he slid in and out, and turned to engage and disengage its stem with respect to the graduated holding means.

The operation of the device may be im proved by providing an inclined batlie or trap 21 in the nozzle 8, this baflie being disposed in front of the open end of the pipe 7, so that a trap chamber 22 is afforded in the rear part of the nozzle, from which liquid escapes by passing through the restricted space between the free edge of this ballle and the back wall of the nozzle. It will be understood that the baflle extends from side wall to sidewall of the nozzle. \Vilh this battle is associated a small air admission tube 23, which opens at its rear end through the back wall of the nozzle and at its forward end opens at or slightly in front of the space between the free end of the baflie 21 and the opposite side of the nozzle. This arrangement produces a gentle flow from the nozzle and contributes to the exactness of the stoppage thereof.

, While I have shown and described a form of my apparatus for dispensing predetermined quantums of liquid, in which the amounts discharged may be varied by ad jusling the capacity of the controlling chamber, I ,(vish it to be understood that 'the device may be made adjustable in other ways, or that it may be constructed as a fixed mea 'ure. Thus, if all of the walls of the contr lling chamber are immovable, instead of having one of them mo yablet' that is to say the piston 15, the device can deliver onl a fixed amount of liquidi The F amount 'bf liquid that will be discharged from the apparatus at any one time may be predetern'lined by the extent to which the pipe or tube 11 projects into the controlling chamber, as well as by the actual capacity of that chamber, because the further the said tube projects into the chamber the sooner its end will be covered by the liquid entering .the chamber during the pouring operation, and the sooner, therefore, will the admission of air to the bottle beflcut of, so as to stop the flow through the delivery spout.

What is claimed as new is:

1. An attachment for dispensing the contents of a bottle in predetermined uantums, comprising two separate and in ependent outlets from the bottle", a delivery nozzle communicating with one of them, a controlling chamber communicating with the other, and means for supplying the bottle with air by way of said chamber until cut off by the liquid admitted thereto.

2. An attachment for dispensing the contents of a bottle in'predetermined quantums, comprising a holder to be inserted in the neck of a bottle, two small tubes to receiveliquid from the bottle projecting forwardfrom said holder, an enlarged delivery nozzle on the end of'one of said small tubes,

. a trap in said nozzle, a controlling chamber into which the other tube delivers, said chamber having an air inlet, and an air tube leading from said chamber through said holder into theiinterior of the bottle.

3. An attachment for dispensing the contents of a bottle in predetermined quantums,

.lO- gomprisinga delivery nozzle, a controlling chamber arranged to receive; liquid from the bottle simultaneously with the discharge of liquid from said nozzle, separdle outlets In witness whereof I have signed my name 20 in the presence. of two subscribing witnesses.
